I began to think that the labyrinth in the nave at Chartres can serve as a symbolic map or metaphor for the pilgrimage. Once we enter it, ordinary time and distance are immaterial, we are in the midst of a ritual and a journey where transformation is possible; we do not know how far away or close we are to the center where meaning can be found until we are there; the way back is not obvious and we have no way of knowing as we emerge how or when we will take the experience back into the world until we do. There are no blind ends in a labyrinth, the path often doubles back on itself, the direction toward which we are facing is continually changing, and if we do not turn back or give up we will reach the center to find the rose, the Goddess, the Grail, a symbol representing the sacred feminine. To return to ordinary life, we must again travel the labyrinth to get out, which is also a complex journey for it involves integrating the experience into consciousness, which is what changes us.
